The kernel fails to set up the resources for the GPU's BAR1. It would be good to check that the SBIOS assigned reasonable memory ranges to all of the GPU's BARS, and set up the upstream bridges correctly. For what it's worth, 0x10000000 bytes (256MB) is reasonable for BAR1, but the resources printed in the first line of the above output seem to include only BAR0 (16MB) and BAR2 (32MB).
